Matthew 26:46

And he left them, and went away again, and prayed the third time, saying the same words.

Then cometh he to his disciples, and saith unto them, Sleep on now, and take your rest: behold, the hour is at hand, and the Son of man is betrayed into the hands of sinners.

And while he yet spake, lo, Judas, one of the twelve, came, and with him a great multitude with swords and staves, from the chief priests and elders of the people.

Now he that betrayed him gave them a sign, saying, Whomsoever I shall kiss, that same is he: hold him fast.
